Abstract

A dental restoration system is disclosed. The system includes an implant having a tip and an opposite cylindrical socket. The socket has an interior surface having a sloped rim surface and a groove with a vertical and horizontal channel. The system includes a dental component such as an abutment having a stem and an opposite post. The post includes a collar having a radial tab. The collar is attached to a conical interface surface. The tab slides in the vertical channel when the abutment is attached to the implant. The tab fits in the horizontal channel of the groove to lock the abutment in place when the abutment is rotated. The conical interface contacts the sloped rim surface of the cylindrical socket to create a seal when the tab is fit into the horizontal channel.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A dental restoration system comprising:
 an implant having a tip and an opposite cylindrical socket, the socket having an interior surface having a sloped rim surface and a groove with a vertical and horizontal channel;   a mating component having an interface section including a collar having a radial tab, the collar being attached to a conical interface surface;   wherein the tab slides in the vertical channel when the mating component is inserted into the implant and the tab fits in the horizontal channel of the groove to lock the mating component in place when the mating component is rotated, and the conical interface contacts the sloped rim surface of the cylindrical socket to create a seal when the tab is fit into the horizontal channel.   
     
     
         2 . The system of  claim 1 , wherein the mating component is an abutment having a stem and an opposite post. 
     
     
         3 . The system of  claim 1 , wherein the mating component is a driver. 
     
     
         4 . The system of  claim 1 , wherein the mating component is an impression coping. 
     
     
         5 . The system of  claim 2 , wherein the abutment is fabricated from titanium allow and the implant is fabricated from commercially pure titanium. 
     
     
         6 . The system of  claim 1 , wherein the collar is substantially the same height as the radial tab. 
     
     
         7 . The system of  claim 1 , wherein the collar includes five tabs and the socket includes five corresponding grooves. 
     
     
         8 . The system of  claim 1 , wherein the horizontal channel has a bottom surface at an angle to the horizontal plnae. 
     
     
         9 . A method of connecting a mating component to an implant, wherein implant has a tip and an opposite cylindrical socket, the socket having an interior surface having a sloped rim surface and a groove with a vertical and horizontal channel, and wherein the mating component has an interface section having a collar having a radial tab, the collar being attached to a conical interface surface, the method comprising;
 inserting the interface section in the cylindrical socket such that the radial tab aligns with the vertical channel of the groove;   moving the mating component so the radial tab slides down into the vertical channel; and   turning the mating component so the radial tab slides into the horizontal groove and the sloped rim surface of the implant contacts the conical interface of the mating component to create a seal.   
     
     
         10 . The method of  claim 9 , wherein the mating component is an abutment having a stem and an opposite post. 
     
     
         11 . The method of  claim 9 , wherein the mating component is a driver. 
     
     
         12 . The method of  claim 9 , wherein the mating component is an impression coping. 
     
     
         13 . The method of  claim 10 , wherein the abutment is fabricated from titanium alloy and the implant is fabricated from commercially pure. 
     
     
         14 . The method of  claim 9 , wherein the collar is substantially the same height as the radial tab. 
     
     
         15 . The method of  claim 9 , wherein the collar includes five tabs and the socket includes five corresponding grooves. 
     
     
         16 . The method of  claim 9 , wherein the horizontal channel has a bottom surface at an angle to the horizontal plane.
